Which Mac and what is its OS release? Also how are you connecting to it via cable or Bluetooth?

2015 macbook pro (macOS high sierra 10.13.6), via bluetooth.

i contact the jbl support, they told me you should rest the speaker by holding vol+ and play/pause button. it didn't work also..

I have a UE Boom2 which sounds great over Bluetooth so it’s got to be the JBL’s firmware as I had some issues with mine (lip sync was off) and the update fixed it. Ask JBL how to update it.

I have the same issue on my 2013 rMBP. The sound has a lot of noise.
